Answer 2

The blast furnace is typically divided into three main zones: the top zone (stack), the middle zone (bustle), and the bottom zone (hearth). The top zone is where raw materials are charged into the furnace and combustion of coke occurs. The middle zone is where gases and heat transfer occurs, and the bottom zone is where molten metal is collected.
